在微信公众号网页开发中，为什么使用scope=snsapi_userinfo，不弹出授权弹窗
https://open.weixin.qq.com/connect/oauth2/authorize?appid=xxxxxxxx&redirect_uri=https%3A%2F%2Fm.xiaoyiduoduo.com%2FHome%2FWxAnswer&response_type=code&scope=snsapi_userinfo&state=wxAnswer#wechat_redirect&redirect_uri=https%3A%2F%2Fm.xiaoyiduoduo.com%2FHome%2FWxAnswer&response_type=code&scope=snsapi_userinfo&state=wxAnswer#wechat_redirect
已经授权过了 就不会再弹了
